Connect two CPUs to two parallel printers or two serial devices using the 2 x 2 Cross-Matrix Printer Switch (DB25). For parallel operation, use Computer to switchbox cables with 1284 AA male to male connectors or DB25 AA male to male connectors. For connecting to printers, use Switchbox to printer cables with 1284 AB male to male connectors or DB25/CN36 AB male to male connectors. Using parallel CPU port, connects: A. 2 CPUs to 2 parallel printers Using serial CPU port, connects: B. 2 CPUs to 2 serial devices (e.g. modem, mouse, serial printer) Recommended cables for parallel operation: Computer to switchbox cables with 1284 AA male to male connectors Computer to switchbox cables with DB25 AA male to male connectors Switchbox to printer cables with 1284 AB male to male connectors Switchbox to printer cables with DB25/CN36 AB male to male connectors
